OLEDs / Scrolling on NHD-0420CW-AY3(US2066)
« on: January 28, 2016, 03:36:04 PM »
Hello all,

I have a NHD-0420CW-AY3 and I am trying to enable scrolling on line 1.
(page 27 on

I am not having much luck which I think is due to a misunderstanding of how the IS,RE, and SD logic bits are set.
After the OLED is initialized, and text is sent to the screen I am sending the following:

Code: [Select]
command(0x28)  //Set Fundamental Command Set
command(0x2B)  //Set IS, RE to 1
command(0x11)  //Enable scrolling on line 1

Any Thoughts?
